Results and discussion

Vapour pressure
Temp.:
20 °C
Vapour pressure:
< 0 Pa
Remarks on result:
other: No significant weight loss of the test substance was observed below 40°C (i.e. a relatively low vapour pressure was observed). Above 40°C the vapour pressure of the test substance extrapolated to 20°C (293K) was < 1.33 x 10^-8 Pa = < 1.00 x 10^-10 mm Hg.

Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the test substance. No significant weight loss of the test substance was observed below 40°C (i.e. a relatively low vapour pressure was observed). Above 40°C the vapour pressure of the test substance extrapolated to 20°C (293K) was
< 1.33 x 10^-8 Pa = < 1.00 x 10^-10 mm Hg.
